Information recording apparatus, imaging device, information-recording controlling method, and computer program

Abstract

An information recording apparatus for recording data on an information recording medium includes a logical-format-image manager configured to generate logical-format-image data; a logical-format-image storage unit configured to store the logical-format-image data generated by the logical-format-image manager; and a recording controller configured to exercise control so that the logical-format-image data stored in the logical-format-image storage unit is recorded on an information recording medium during periods of suspension of recording of user data on the information recording medium, the periods of suspension being provided intermittently on the basis of an amount of user data stored in a buffer for storing user data.

AI Technical Summary

Benefits of technology

The present invention provides an information recording apparatus, an imaging device, an information recording medium, and a computer program that allow for faster processing and formatting of data when recording on the information recording medium, such as a DVD. The invention provides a method for generating and storing logical-format data on the recording medium without recording the data on the recording medium during initialization. The recording controlling means can exercise control to record the logical-format data on the recording medium during intermittent periods of recording user data, based on the amount of data stored in a buffer. The invention also allows for starting recording of user data without waiting for completion of initialization and allows for input of user data after completion of physical formatting. The technical effects of the invention include faster processing and more efficient use of storage space on the recording medium.

Problems solved by technology

These steps of formatting, executed for initialization of a recording medium, take a rather long time.

Thus, for example, when video data is recorded by a video camera or the like, the user could unfortunately miss a desired scene while waiting for completion of initialization.

According to this method, however, writing to a recording medium occurs before completion of formatting when a request for recording user data is not issued.

In this case, a write error of format data could occur and formatting could fail due to vibration or other factors.

This could result in corruption of data; for example, appropriate recording or playback of user data on the recording medium could fail.
